Revisiting Lock Screen

[Bob Sneidar]

Hi Craig thanks for responding. I am not updating fields per se as the only thing changing is the datagrid selection(s) and the status of the checkbox. 

Curiously I am not seeing the tab widget selection change but I am seeing the hiding and showing of the datagrids as each tab is selected.

Okay so I turn it off, put the command “Lock Screen” at the entry point to a selectionChanged handler which goes on to do a number of things that change the appearance of the screen. The screen is decidedly NOT LOCKED! The things I go on to do are things like changing the hilitedItems of a tab widget which in turn shows and hides a number of objects, and also changes the selection in a number of datagrids. Every action that alters the screen is visible after I issue the Lock Screen command.
